.BUTT-ADJUSTER FOR GRAIN-BINDERS.

SP1?.CIFICA'LIONy forming part of Letters Patent No. 502,210, dated July 25, 1893.

Original application filed October 27, 1892, Serial No. 450,110. Divided and this application filed March 27, 1893. Serial No. 467,792. (No modeLl To all whom-t may concern:

Be it known that I, ANDREW STARK, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Butt-Adjusters for Grain-Binders, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

This application is a division of my application, Serial No. 450,110, filed October 27, 1892.

In the drawings, Figure 1 is a detail plan of so much of the grain binder frame and deck and mechanism thereon as relates to the present invention. Fig. 2 is a front elevation of the same mechanism.

I have shown myimprovements as applied to a front geared binder.

Ais the binder frame in the customary U- form. l

` B represents the deck.

C is a fore-and-aft bar of the harvester frame above the deck.

C and C2 are fore-and-aft bars of the frame below the deck, said bars conventionally representing any rigid part of the harvester frame on which the binder frame is supported and adapted to be moved fore-and-aft.

A and A2 are bracket arms rigid with the binder frame, Which extend to the harvester frame-bars C and C2, respectively, for the purpose of such support.

D is the butting board; D', the arm thereon which extends back to the crank D4, by which the butting board is actuated.

D5 is a pinion rigid with the crank D4 fixed on the shaft d5, from which the butter receives motion. i

Drepresents conventionallyany gear which may be provided to drive the pinion D5, and said gear and pinion are intended to represent conventionally any suitable means for communicating rotary motion to the crank shaft d5.

The features pertaining to this invention, which will now be described, have for their purpose the automatic adjustment of the butting board as the binder is adj usted fore-andaft to accommodate dierent lengths of grain. The binder being, as stated, of the frontgeared type, it is adjusted forward to bring the binder arm to the proper position for short grain, and rearward, to adapt it to longer grain. In the absence of any adjustment of the butting board, the entire difference in the length of the grain, or in the position of the band due to the dierence in the length of the grain,- would have to be provided for by the adjustment of the binder itself. In order to avoid this long range of adjustment, it is desirable to provide for a part of the difference by adjusting the butting board. As the binder, therefore, is adjusted forward, the butting board is adj usted rearward, and the present invention is concerned with devices for causing the forward adjustment of the butter automatically to effect a rearward adjustment of the butting board, and vice versa, to cause the rearward adjustment of the binder automatically to effect the forward adjustment of the butting board. The butting board shown is of a familiar type, having its stubbleward end provided with an eye d, adapted to travel on a guide rod D2, the grainward end of the butting board being connected to the crank D, as described, adapted to give it fore-and-aft movement, while the right and left movement is accommodated by the sliding of the eye on the rod,-as the butting board moves longitudinally. The rod D2 is pivoted at d24 to the bar A2, which is rigid with the binder frame A, and serves to support other parts of the binder, as will be understood without further explanation. For the further support of the bar D2, I provide the bar D3, which is pivotally connected to a fixed portion of the harvester frame, the frame bar C, illustrated, serving that purpose whileV also supporting the elevator hood or over deck c. The bar D3, extending above the over-decke, and being lodged above the bar A2 on which it is adapted to slide as it swings about its pivot in the adjustment hereinafter described, is bent down stubbleward of that bar and has, at its end an eye D30, through which the wrist D20 of the rod passes, said rod being bent, as shown in the drawings, to form such wrist for that purpose. It will be seen that as the binder is moved forward to bring the bar A2 from the position shown in full lines to the position shown in dotted lines, the bar D3 will swing from the position shown in full lines to the dotted line position, a little forward of the full line position, and the rod D2, through which that movement is derived and by which it is controlled, will have its own movement at the wrist D30 controlled also by the bar D3, and being carried forward at its pivot d2 very much more than at its wrist D80, its stubbleward end will swing rearward, the new position being that shown in dotted lines in Fig. 1, the eect being to cause the butter at the stubbleward end to operate at a position which is considerably rearward of the original position. The proportion of the parts and the distance of the several pivots may be such as to make the change of position of the binder in either direction produce about an equal change of position of the butter in the opposite direction. The relation, however, of the two adjustments as to degree is not essential. The most economical result is attained when the adjustment necessary is eected half by the binder and half by the resultant movement of the butter.

I claiml. In combination with a harvester frame, the binder frame movable fore-and-aft thereon, the butter having a support on the binder frame, and connections from such support to the harvester frame adapted to cause foreand-aft adjustment of the binder to communicate a reverse movement to the butter: substantially as set forth.

2. In a harvester, in combination with the main harvester frame, the binder frame movable fore-and-aft on the harvester frame, and the butter deriving support on the binder frame and deriving movement from the mechanism on the harvester frame, and connections from the butter support to the harvester frame elsewhere than at the point at which the butter derives movement,whereby the adjustment of the binder produces a contrary adjustment of the butter: substantially as set forth.

3. In combination with a harvester frame, the binder-frame movable fore-and-aft on the harvester frame, the butter and a guide rod for the same pivoted on the binder frame, and a controlling bar or link pivoted on the harvester frame and pivotally connected to said butter guide rod at a point stubbleward from the pivot of the latter: substantially as set forth.

4. In combi nation with the harvester frame, the binder frame movable fore-and-aft thereupon; aorank arm of a shaft journaled on the harvester frame, and the butter actuated at one end by such crank arm and guided at the other end; the guide rod for such butter being pivoted on the binder frame, and a link or bar which controls the position of such guide rod pivoted on the harvester frame rearward of the said guide rod and pivotally connected to said guide rod at a point between the pivot of the latter and the guide connection of the butter thereto: substantially as set forth.

In testimony whereof I have hereunto set my hand, at St. Louis Park, Minnesota, this 22d day of March, 1893, in the presence of two witnesses.
